OAR-LOCK.

SPECIFICATION forming part of Lettersratent No. 772,264, dated otober11, 1904. Application led December 24, 1903. 4 Serial No. 186,417. (Nomodel.)

To all whom, t may 0071.067471.: v

Be it known that I, HENRY W. WHEELER, a citizen of the United States,residing at Syracuse, in the county of Onondaga andv Stateof New York,have invented aD new and useful Improvement in Oar-Locks, of which thefollowing is a speciiication.

This invention relates to oar-locks, and has for its object a lock ofthis character which will be simple and light in construction and at thesame time strong enough to stand any reasonable strain that may be putupon it.

A further object is a lock adapted for feathering and practicallynoiseless in its operation.

My invention consists in the novel features of construction andcombination of parts hereinafter described, particularly pointed out inthe claim, and shown in the accompanying drawings, in which- .Y l

Figure 1 is a perspective view of my device, showing same applied to aboat. Fig. 2 is a detail sectional view taken transversely through thegunwale of the boat, the tholepin being shown partly in elevation and aportion of the oar being shown in elevation. Fig. 3 is a section on theirregular line 3 3 of Fig. 2. Figs. 4 and 5 are end elevations ofslightlymodified forms of locks.

In applying this device the gunwale of the boat is cut away, as shown atA in Figs. l, 2, and 8, and in this cut-out portion is inserted a plateB of some thickness, flanged at its upper end, the flanges B extending aconsiderable distance longitudinally, and these iianges are held inplace on the gunwale by suitable bolts and nuts, as shown in Figs. land3. The plate B has a vertical cylindrical slot B2, formed in it midwayits ends, the slot being upwardly and downwardly open, and at its lowerend it is .closed by a plate B3, fastened by screws to the lower end ofthe plate B. The slot B2 is enlarged at each end, so that a cup-likereceptacle is provided at each end of the slot for theantifriction-balls B4, the balls at the lower end resting on the plateB3. An aperture is formed in the front of the plate B, which intersectsthe slot or bore B2. To the front of the plate B is secured an invertedtriangular-shaped spring B5, secured at its tion of the non-reduced partof the thole-pin turning on the upper set of balls B4. An annular grooveC is formed around the reduced portion of the thole-pin, the groovealining with the aperture in the plate and the pin BG extending intosaid groove. To retract the pin by lifting the spring-plate B5 outward,a ring B7 is secured to the lower end or apex of the spring. The upperportion of the tholepin is enlarged into a head C2, and formed on thishead intermediate its ends are a pair of lugs C3, transverselyperforatedj A cylindrical sleeve D is slightly enlarged or flared andopen at each end. Intermediate its ends the sleeve carries threedepending lugs D', arranged in alinement and transverse to the bore ofthe sleeve. These lugs are perforated to aline with the perforations inthe lugs C3,

the central lug D' fitting between the lugs C3.'

These two sets of lugs are pivotally connected by a suitable bolt andform a compact and durable knuckle-joint allowing a swinging verticalmovement of thesleeve ends. To the rounded portion of the oar which isto be held in the sleeve D is secured a second sleeve E, which lits theoar snugly and is held against longitudinal movement on the oar bysuitable screws countersunl; in the sleeve E. This sleeve is longer thanthe sleeve D and is exteriorly threaded adjacent each end, theintermediate portion being smooth and adapted to rotate loosely within4the sleeve D. To prevent longitudinal movement of the-sleeve E in thesleeve D and consequent sliding of the oar with reference to the sleeveD, jamnuts F are threaded on each end of the sleeve E, and washers F arealso arranged on .the sleeve E and fit between the ends of the sleeve Dand the jam-nuts F. These sleeves are slightly beveled or curved ontheir inner face and rest within the enlarged portions of the sleeve D.

Suitable antirictionballs G are arranged in each end of the sleeve D andare held in place by the 'washers F.

In Fig. 4: I have shown a form of sleeve H adapted for use with asquared oar. This sleeve H has the three depending lugs H',corresponding With the lugs D of the sleeve D. The lug H is formed intwo sections, the main section having outwardly extending side flangesH2, and the other section consists of a plate H3, which rests on and isbolted to these flanges. In the remaining Fig. 5 I have shown a simpleform of sleeve J, adapted for use with a round oar. This sleeve iscylindrical in form and is longitudinally divided into two halves, eachbeing longitudinally flanged on each side and the ianges boltedtogether. It is also provided with the depending lugs, and both thesleeves H and J are used in connection with the plate B and thethole-pin C.

It will be obvious from the above that I have an oar-lock that willpermit feathering of the oar, vertical movement of the oar while at anyangle to the gunwale, and also by rotation of the thole-pin in the boreB2 the required horizontal sweep of the oar, and, further, that suchmovements will not cause any wear or tear on the part of the oar lockedto the gunwale. To remove the oar from the boat or from its position onthe gunwale, it is only necessary to pull'on the ring B7 and the pin BGwill be drawn outward, disengaging the groove C of the thole-pin, andthe pin may be lifted from the bore of the plate B2, the said borepractically forming asocliet for the thole-pin.

The oar K may be round or squared, depending on the form of sleeve withwhich it is used; but in' no case is it necessary to cut away thev oar,and thus reduce its diameter and weaken it, in order to secure thesleeve to it.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination with an oar, of a sleeve secured thereto and threadedadjacent each end, a second shorter sleeve adapted to receive thefirst-mentioned sleeve, said second sleeve having depending lugs formedintegral with it, a thole-pin having ahead portion carrying lugs adaptedto lit between the lugs of the second-mentioned sleeve, a bolt passingtransversely through said lugs, washers adapted to lit over thefirst-mentioned sleeve and to close the ends of the second sleeve,jam-nuts adapt- .ed to be threaded on the irst-mentioned sleeve and bearon the washers, and means for securing the thole-pin to the gunwale ofthe boat.
